    摘要: A direct-injection internal combustion engine is fluidly coupled to a passive SCR system including a three-way catalytic converter upstream to an ammonia-selective catalytic reduction catalyst. Transition from an HCCI combustion mode to an SI combustion mode includes determining a preferred air/fuel ratio to achieve a minimum fuel consumption and maintain combustion stability at an acceptable level for a predetermined engine operating point during the SI combustion mode. A fuel injection timing, an engine spark timing and an engine valve lift are substantially immediately controlled from respective HCCI combustion mode settings to respective SI combustion mode settings. A transition to the preferred air/fuel ratio is coordinated with a transition of an engine valve phase from a respective HCCI combustion mode setting to a respective SI combustion mode phase setting.

    摘要: A method for controlling ammonia generation in an exhaust gas feedstream output from an internal combustion engine equipped with an exhaust aftertreatment system having a first aftertreatment device includes executing an ammonia generation cycle to generate ammonia on the first aftertreatment device. The ammonia generation cycle includes monitoring an air-fuel ratio in the exhaust gas feedstream at a first location in the exhaust aftertreatment system, and monitoring an air-fuel ratio in the exhaust gas feedstream at a second location in the exhaust aftertreatment system. The air-fuel ratio at the first location is compared to the air-fuel ratio at the second location. If the air-fuel ratio at the second location is richer than the air-fuel ratio at the first location, operation of the engine is adjusted until the air-fuel ratio at the second location is equal to the air-fuel ratio at the first location.

    摘要: A system for a vehicle includes a mode control module and a valve control module. The mode control module selectively sets an ignition mode for an engine to one of a spark ignition (SI) mode and a homogenous charge compression ignition (HCCI) mode. In response to the ignition mode transitioning from the SI mode to the HCCI mode during a first engine cycle, the valve control module operates an exhaust valve in a high lift mode during a second engine cycle, operates an intake valve in a low lift mode during the second engine cycle, and operates the exhaust and intake valves in the low lift mode during a third engine cycle. The first engine cycle is before the second engine cycle, and the second engine cycle is before the third engine cycle.
